Angular Displacement, Velocity, Acceleration

Crista Ampullaris (start of semicircular canals) detect angular acceleration. At each ampullae there is hair cells with cilium and stereocilim, sticking up in the cupula (round circle filled with fluid). Each semicircle canal resides in frontal, horizontal, and saggital plane to detect all direction of rotations. As head turns, endolymph (fluid) lags behind, pushes capula, and stimulate the hair cells.

Comparison of the effects of inertia on (from back to front) a hollow spherical shell (red), a solid ball (orange), a ring (green), & a solid cylinder (blue). "An object's moment of inertia determines how much it resists rotational motion. In this simulation, four objects are placed on a ramp and left to roll without slipping. Starting from rest, each will experience an angular acceleration based on their moment of inertia." Caption from link. Click through for animation

### Angular Kinematics

Presentation about angular motion. Covers angular distance, angular velocity, angular acceleration, angular momentum, torque, moment of inertia and more.

A star meets a black hole. As the star approaches, the gravitational pull of the black hole and the angular acceleration exceeds the strength of the gravity of the star for holding itself together—a point called the Roche Limit. The plasma of the star abruptly unspool into space in filaments billions of miles long. The threads are not dense enough to maintain fusion, so begin to cool and darken: this is the star’s swan song, it’s body spread too thin to maintain its former luminous…

### Physics - Rotational Motion Software - PC Version

ROTATIONAL MOTION LECTURE SOFTWARE Rotational Motion is a software based lecture aid covering the following: the definition of radians and the conversion to degrees, the derivation and definition of angular velocity and angular acceleration, and the similarity of the linear and rotation motion equations. The lecture screens are set up in a step by step fashion and there are a number of simulations to help illustrate the fact that many of the variables are related.
